La ley de asimetría

La ley de asimetría is Mario’s second “small law” of eroticism, formulated as a direct challenge to the assumption that pleasure is best sustained by balance, privacy, or symmetrical exchange. In his account, erotic life begins where equilibrium fails: difference creates tension, spectatorship, invention, and the possibility of transforming bodily relations into an art. The law belongs to the intellectual architecture of Emmanuelle. La leçon d'homme, where Mario presents eroticism not as a collection of sexual techniques but as a rational, confident, life-affirming code and a form of education.

Definition and Place in Mario’s Theory

Mario introduces the law while discussing the danger that familiarity may weaken pleasure. He argues that eroticism needs asymmetry, then distinguishes this principle from the first “small law,” La ley de lo insólito, which depends on novelty or the unusual. Both are subordinate to what he calls the single great law: sovereign simplicity. La ley de asimetría therefore operates as a secondary condition within a larger system, but it has a precise function. Where the unusual interrupts habit, asymmetry prevents erotic relations from settling into balance and repetition.

The principle is not presented as a moral command imposed from outside. Mario describes eroticism as a measure, canon, code, ceremonial, art, and school, even calling it the outcome of a choice grounded in reason rather than credulity, confidence rather than fear, and love of life rather than a mystique of death. Within that framework, asymmetry is less a prohibition than a structural demand: erotic intensity needs an uneven arrangement capable of keeping desire open.

Biological Metaphor and the Rejection of Equilibrium

Mario explains the law by borrowing the language of science. He says that the emergence of living cells depended on large protein molecules whose components were arranged with a high degree of asymmetry. In this account, no superior organization of matter, and therefore no progress, is possible without an initial imbalance. Biological inadaptation later becomes another decisive factor in evolution. Eroticism, described as an advanced phase of that evolution, is consequently governed by the same tendencies.

The conclusion is emphatic: life, and therefore eroticism, feels horror toward equilibrium. The metaphor makes asymmetry more than a social preference or an aesthetic taste. It places erotic desire within a speculative history of matter and life, allowing Mario to recast imbalance as a generative force. What appears disordered from the standpoint of conventional morality becomes, in his rhetoric, the very condition through which organization, development, and invention occur.

Asymmetry as Spectatorship and Artistic Form

Mario then shifts from biology to art. For an erotic act to have an audience, he argues, asymmetry must return; one example is that the number of people making love should be odd. The uneven number creates a relation between performers and observers, preventing the scene from becoming a closed exchange between equal partners. The presence of an outsider supplies a new angle of attention and therefore a new horizon of pleasure.

This logic also explains his earlier claim that children among the Murias make love before their companions or visiting guests. Two people alone in a room might become bored, whereas the gaze of others can reveal possibilities that familiarity conceals. The spectator is not merely an intruder but part of the erotic composition. Asymmetry distributes roles unevenly, and that unevenness converts intimacy into a scene with an audience, a changing perspective, and an artistic dimension.

Mario’s most compact example is masturbation. One person is an odd number, he observes, because the masturbating subject is actor and spectator at once. The act is therefore “eminently erotic” in his system: a work of art in which the division between performer and viewer is contained within a single body. The apparent symmetry of a solitary act conceals an internal asymmetry, since the subject occupies two positions at once. This dual role makes exclusivity possible without eliminating spectatorship.

Sexual Difference, Convention, and the Body as Material

La ley de asimetría is linked to Mario’s broader insistence that eroticism can challenge nature without simply denying the body. He describes sex between women as biologically impossible in the conventional reproductive sense, yet says that erotic invention makes the dream a reality. He similarly treats sex among five people as unnatural and therefore available to human imagination, arrangement, and realization. In both examples, eroticism is defined by the capacity to organize relations that nature does not prescribe.

That argument extends into Mario’s theory of eroticism as the highest art of a spacefaring human age. Earlier arts shaped colors, curves, sounds, stone, bronze, or paste; the new art shapes living bodies and minds. He asks whether there is a more penetrating art than taking the human body and turning a natural work into an altered human work. To seize the body is, in his formulation, not merely to approve, love, or enjoy its natural form, but to contest and remake it, freeing the human being from the blind determinism of the cell and from the laws that reduce a person to meteor or molecule.

Asymmetry thus names both an erotic arrangement and a cultural rebellion. It resists the balanced, self-contained model of sexuality; it also resists the idea that nature supplies the final standard of what human beings may imagine. Mario’s rhetoric makes eroticism a form of courage, opposed to fear of difference, fear of thought, and fear of happiness. The law’s deepest stake is consequently not numerical but philosophical: unequal positions and deviations from equilibrium make self-created freedom conceivable.

Legal and Religious Counterforces

The principle is sharpened by its proximity to prohibition. When Emmanuelle asks whether smoking opium is forbidden, Mario answers that it is, just as making love outside marriage is forbidden. When she asks what they would do if the police arrived, he states that they would go to prison. The law of the state therefore stands beside marital and moral convention as an opposing order, one capable of converting erotic experimentation into criminal consequence.

The contrast does not disappear in a religious setting. At a temple, Emmanuelle sees strange fruits hanging from a great tree and realizes that they are phallic offerings. Mario explains that some are ex-votos and others are offerings for sexual potency or fertility, with their size determined by the worshipper’s wealth or by the urgency of the prayer. The objects reveal a ritual system that acknowledges sexual desire while regulating it through devotion, exchange, wealth, and petition. Against such forms of sanctioned fertility, Mario’s asymmetrical eroticism proposes a different organization of desire: not reproductive balance or institutional legitimacy, but conscious arrangement, audacity, and the transformation of convention.

La ley de asimetría therefore occupies a productive contradiction in the book. It is formulated as a rule, yet it favors disequilibrium; it belongs to a moral code, yet it contests marriage, police authority, and religious convention; it invokes science, yet it culminates in an art of bodies and minds. Its force lies precisely in converting imbalance into a principle of order. In Mario’s theory, eroticism does not become free by abandoning all structure. It becomes free by choosing structures that refuse the supposedly natural equilibrium imposed by biology, custom, and fear.
